The Short-Term Remission of Diabetic Nephropathy After Roux-en-Y Gastric Bypass in Chinese Patients of T2DM with Obesity

The study aimed to examine the effect of gastric bypass on diabetic nephropathy (DN) in Chinese patients. A retrospective study of 101 samples with DN stages I to IV underwent Roux-en-Y gastric bypass. Anthropometric and biochemical parameters were assessed during a 1-year follow-up. Binary logistic regression analysis was used for predictors and ROC for cutoff points. There was significant reduction of medication for diabetes and hypertension. Overall remission of T2DM was 80.2 %. Preoperative albumin/creatinine ratio (ACR) and serum creatinine (SCr) levels could be predictors for DN remission, and the cutoff points were 126 mg/g cr and 57 mu mol/L, respectively. Gastric bypass showed improvement of T2DM and DN. Gastric bypass may be more beneficial for those with lower preoperative ACR and SCr.
